United States Patent 3,289,455 CRIMPING PLIERS Ronald J. Pisko, 2165 Westminster Ave., Camden, N.J., and John Weiss, Old Marlton Pike, RD. 2, Marlton,

Filed May 26, 1964, Ser. No. 370,310 Claims. (Cl. 72-409) This invention relates to the electronics industry, and more particularly to that branch of the industry that has to do with the manufacture of computers, and still more particularly to a hand tool used in this work as will hereinafter be described.

As nearly anyone having knowledge of the manufacture of electronic computers knows, this work entails a considerable amount of tedious hand work, particularly when it comes to the securement of wires to that part of the computer known as the pins.

It is therefore the primary object of this invention to provide a hand tool in the form of crimping pliers that will successfully crimp the ends of the wires to the pins before they are soldered to the same.

Another object of this invention is to provide crimping pliers specially designed to do this given job of crimping the ends of wires to pins in a minimum amount of time.

Another object of this invention is to provide crimping pliers that will uniformly crimp the ends of wires to the pins of an electronic computer.

Another object of this invention is to provide crimping pliers that will successfully do the desired job of crimping the ends of the wires to the pins without interferring with other pins and wires on the same assembly.

Still another object of this invention is to provide crimping pliers that will not damage either the pins or the wires while crimping the same together.

Other objects and purposes of this invention will become apparent to persons acquainted with the securement of the ends of the wires to the pins in electronic computers upon reading the following disclosure and inspection of the several views of the accompanying drawing in which:

FIGURE 1 is a side view of this invention.

FIGURE 2 is a top view of this invention.

FIGURE 3 is a pictorial view of the nose of this ininvention.

FIGURE 4 is a pictorial view of the nose of this invention crimping the end of a wire on a pin.

FIGURE 5 is a sectional view of a portion of FIGURE 4 taken along line 5-5 and viewed in the direction indicated by the arrows.

Referring now to the accompanying drawing, reference is made to FIGURE 1 where it is seen that the numeral 7 indicates the crimping pliers which embodies a body member 8 having a handle 9 and a nose 10 that is rectangular in cross-section at the rear end 11 thereof and half-round at the front end 12 which is provided with a centrally located longitudinally disposed rectangular recess 13. The body member 14 is identical to that of the just described body member 8 to which it is swingably secured by the pin 15. All associated parts of the aforesaid body member 14 that are identical to that of the aforesaid body member 8 are indicated on the drawing by like reference numbers to that already used to indicate like parts of the body member 8, with the exception of the nose 10 which on body member 14 is characterized by the reference numeral 16 since this nose is provided with a concave recess 17 in the upper face 18 that extends backward longitudinal to a point 19 that is clearly indicated in the accompanying drawing.

The way in which this invention of crimping pliers is used is fully understood by any previous user of pliers when examination is made of FIGURES 4 and 5 of the drawing where it is shown that the nose 10 of the pliers 7 is placed over one of the pins 20 that projectupward from the block 21 and to which it is desired to secure one pre-looped end of the wire 22. The aforesaid pins 20 have a configuration of what is best described as being the half of a tube when viewed from the end. The pin 15 obviously will fit into the longitudinally extending concave recess 17 in the nose 10 of the body member 14. The wire 22 which has had its insulation 23 removed from its end will extend horizontally outward through the recess 13 of the nose 10 of the crimping pliers 7 when the nose of the pliers has been placed over the pin 20 and the wire 22. The squeezing together of the two handles 9 of the crimping pliers will now force the bare end of the wire 22 around the lower end of the pin 20 and thereby provide excellent and near contact with the pin to which it is now soldered in the usual manner. It can now be seen at a glance that when all the wires 22 are thus secured to the pins 20 projecting vertically upward from the aforesaid block 21 that they will be uniform, something that could not otherwise be obtained without the use of this novel crimping and time-saving pliers. No amount of time-consuming hand forming of the ends of the wires 22 to the pins 20 can possible produce the neat tight fit of the wires to the pins, something that is most desired and in fact necessary in construction of this nature where space is at a premium and where the wires cannot under any condition be allowed to touch one another.

Attention should be called to the fact that the longitudinal center line of the aforesaid rectangular recess 13 is in line with the longitudinal center line of the concave recess 17 in order to achieve the proper alignment of the two recesses in relation to the pin 20 and wire 22 when the nose of the crimping pliers 7 is placed on the same in the above described way in which this crimping pliers is used.

It will be understood that the embodiments described herein are merely illustrative of the invention and that modifications thereof may be made without departing from the scope of the invention.

What is claimed is:

1. Crimping pliers of the character described, comprising two body members swingably hinged together by a pin, each said body member having a tapering nose from one of which extends a recess at right angle thereto and from the other of which longitudinally extends a concave recess in the upper face thereof, the first mentioned recess being adapted to fit over a given pin and the second mentioned recess being adapted to fit over the bare end of a wire looped around the said pin to which it is desired to crimp the same thereto when the said body members of the said crimping pliers are manually squeezed together.

2. Crimping pliers of the character described, comprising two body members, each having a handle, that are swingably hinged together by a pin, each said body member having a tapering nose from one of which extends a recess at right angle thereto and from the other of which longitudinally extends a concave recess in the upper face thereof, the first mentioned recess being adapted to fit over a given pin and the second mentioned recess being adapted to fit over the bare end of a wire looped around the said pin to which it is desired to crimp the same thereto when the said body members of the said crimping pliers are manually squeezed together by their handles.

3. Crimping pliers of the character described, comprising two body members, each having a handle, that are swingably hinged together by a pin, each said body member having a tapering nose that is rectangular in cross-section at the rear end and half round at the front end and from one of which extends a recess at right angle thereto and from the other of which longitudinally extends a concave recess in the upper face thereof, the first mentioned recess being adapted to fit over a given pin and the second mentioned recess being adapted to fit over the bare end of a wire looped around the said pin to which it is desired to crimp the same thereto when the said body members of the said crimping pliers are manually squeezed together by their handles.

4. Crimping pliers of the character described, comprising two body members, each having a handle, that are swingably hinged together by a pin, each said body member having a tapering nose that is rectangular in crossseotion at the rear end and half round at the front end and from one of which extends a rectangular recess at right angle thereto and from the other of which longitudinally extends a concave recess in the upper face thereof, the first mentioned recess being adapted to fit over a given pin and the second mentioned recess being adapted to fit over the bare end of a wire looped around the said pin to which it is desired to crimp the same thereto when the said body members of the said crimping pliers are manually squeezed together by their handles.
